What to write to my older self?

If I was able to write to my older self I want to ask a lot of stuff about how life become. Will the things I think are hard now be easy when I grow up? What is my work? How much do I get payed? How many kids do I have? Who am I married to? Am I a happy person with villa, volvo and a dog? Will I have the same friends today like when I grow up?

 

What if I get the answers? If I don't like them then maybe I think I will change my decisions and then the answers will not be right anyways.
